We exploit the information content of option prices to construct a novel measure of bank tail-risk. We document a persistent increase in tail-risk for the U.S. banking industry following the global financial crisis, except for banks designated as systemically important by the Dodd-Frank Act. We...

We use tools of extreme value theory to extract information about rare events from market prices. We find that such information contributes materially to measures of banks' systemic importance. These measures exhibit strong and intuitive relationships with simple characteristics of banks'...

This paper exploits the information content of option markets to offer fresh insight into the Too-Big-to-Fail (TBTF) problem for banks. I employ option prices to construct a forward-looking measure of bank exposure to significant price drops (i.e. tail-risk) and explore cross-sectional...

Since increasing a bank's capital requirement to improve the stability of the financial system imposes costs upon the bank, a regulator should ideally be able to prove beyond a reasonable doubt that banks classified as systemically risky really do create systemic risk before subjecting them to...

We measure a systemic risk faced by European banking sectors using the CoVaR measure. We propose the conditional value-at-risk (CoVaR) for measuring a spillover risk which demonstrates the bilateral relation between the tail risks of two financial institutions. The aim of the study is to...

Building on previous research, we study banks’ balance sheet year-end patterns in the European Union (EU) to assess the impact on supervisory measures of their systemic importance. We find that some global systemically important banks (G-SIBs) in the EU compress their balance sheet at year-end...

We develop a measure of systemic importance that accounts for the extent to which a bank propagates shocks across the banking system and is vulnerable to propagated shocks. Based on Shapley values, this measure gauges the contribution of interconnected banks to systemic risk, in contrast to...

We study banks’ year-end window dressing in the European Union to assess how it affects the identification of global systemically important banks (G-SIBs) and the associated capital surcharges. We find that G-SIBs compress their balance sheet at year-end to an extent that they can reduce their...

We construct a new systemic risk measure that quantifies vulnerability to fire-sale spillovers using detailed regulatory balance sheet data for U.S. commercial banks and repo market data for broker-dealers. Even for moderate shocks in normal times, fire-sale externalities can be substantial. For...

Frictions prevent banks to immediately adjust their capital ratio towards their desired and/or imposed level. This paper analyzes (i) whether or not these frictions are larger for regulatory capital ratios vis-à-vis a plain leverage ratio; (ii) which adjustment channels banks use to adjust...
